FOLS Manual Groove butterfly valve

FOLS Manual Groove butterfly valve

This product is a new type of valve developed by our company. It has a quick installation, simple and reliable, light weight, convenient maintenance and so on. Especially it has better sealing characteristic of eccentric butterfly valve, and has a quick connection with the tube of the wish. It can be widely used in pipeline, such as water supply, drainage, fire protection, petroleum, chemical industry, medicine, steel and so on.

Material advantages and applications

·  The hoop butterfly valve seal adopts the latest technology design abroad, which is eccentricity. After the seal is pressed, the seal is closed with less movement and lighter friction (basically no friction), so it wears less and is durable.

·  The butterfly plate adopts the first class European rubber vulcanization technology, making the butterfly plate encapsulating the whole glue, which can ensure the exact geometric size of the butterfly plate, and have strong interchangeability and corrosion resistance.

·  The powder epoxy resin coating is used inside and outside the valve body to prevent the corrosion of the valve body and the phenomenon of iron water in the hair.

·  The valve stem and valve body adopt three "O" type ring seal ring seal design, which greatly reduces the friction resistance during the switch, and greatly reduces the leakage. It is the valve does not leak frequently.

·  The Groove type butterfly valve is compact in structure, small in volume, light in weight, flexible in operation and convenient in maintenance.

·  The design adopts the principle of eccentric bidirectional seal, the sealing performance is reliable, and the flow direction is not limited.

·  The overflow area is large, the flow resistance coefficient is small and the circulation ability is big.

·  Anti aging, anti radiation, durable

Installation Instruction

·    Verify that the valve breakaway torque is less than the rated output torque of the actuator.

·    Any mechanical stops that would interfere with the operation of the actuator must be removed before installation of the actuator,i.e.lever,travel stops,etc.

·    The actuator output coupling must be centered with the valve stem to prevent side loading, which causes premature stem packing wear.

·    To use the manual override feature (identified on cover label), the override shaft must be pressed down firmly at least 1/4" in order to disenaage the motor from the gears. The manual override is not designed to overcome torque in excess of the rated torque of the actuator. Serious damage to the gear system may result from excessive turning force on the manual override.

·    This Series actuator may be mounted in any position, i.e.horizontal, upside down. If the conduit entrance points upward, conduit piping must be oriented as to prevent condensation from entering the actuator from the conduit pipe.
